The difference between Static Random Access Memory and Dynamic Random Access Memory is in the way they hold data: DRAM requires data to be refreshed at regular intervals while SRAM does not require data to be refreshed periodically as long as the power supply remains intact. For this reason, the two types of RAM are also structurally different.Know More
SRAM and DRAM are the two types of random access memory and each has its own pros and cons. DRAM is generally slower than SRAM due to the additional circuitry needed for the data refresh cycles.
A DRAM chip comprises several memory cells. Each cell holds only one bit of information and is made of a capacitor and a transistor. Of course, these are extremely minute parts and thousands of them can fit into a single memory chip. One major complication introduced by the additional circuitry in DRAM is that it requires more power to refresh the data. This difference has significant implications in devices that use batteries.
The technology used in SRAM requires the memory cell to have more transistors in order to hold a specific amount of data. For this reason, a memory cell in SRAM eats up more space on a chip compared to a dynamic memory cell. Thus, SRAM gives users less memory per chip and brings about a big cost difference between the two.
In short, SRAM is fast and pricier while DRAM is slower and cheaper.Learn More
According to the University of Mexico, serial ports transmit data one bit at a time, whereas parallel ports transmit 8 bits of data at a time. The location of the port depends on the age and type of the device.Full Answer >
There are many reasons why a PC unexpectedly shuts down, but the most common reasons involve problems with the power supply. It is possible that the battery is failing to hold a charge, or the charger may be malfunctioning. Another common cause is an overheated CPU. Check to see if there is dust or anything blocking the fans on the bottom of the computer.Full Answer >
The important components of a computer are the CPU, memory, graphics adapter, storage system and power supply. The motherboard connects these components together inside the case. Outside the case, the input system includes a keyboard and mouse, and the output display is usually a monitor.Full Answer >
Serial advanced technology attachments (SATA) work by transmitting data between a motherboard and hard drives through a seven-pin cable that sends information twice as fast as previous technology, according to About.com. A single high-speed serial wire now inhabits most computer systems instead of a parallel bus system that incorporated 40-pin wires or 80-pin wires.Full Answer >
